vi PREFACE TO THE FIFTH EDITION. 



the chapter on General Anatomy have been borrowed from the English trans- 

 lation of Kolliker's "Manual of Human Microscopic Anatomy," from the 

 " Entwicklungsgeschichte" of the same author, Todd and Bowman's " Physi- 

 ology," Harley and Brown's " Demonstrations of Microscopic Anatomy," and 

 other well-known works : the source of the drawings having been in each case 

 acknowledged in the Table of Contents. 



The text has been further expurgated from errors of the press; and the 

 Editor has to acknowledge his obligations in this particular to his friend Pro- 

 fessor Darling, of New York, and to Mr. Matthews, of Kirkdale, who have 

 teen kind enough to point out several, and some of them important, clerical 

 errors which had escaped notice in previous revisions.
